I ran my pressure washer the other day to wash my car and truck. I didnt have any regular gas handy so I filled it with E85. Everything ran fine till I got near the end of the tank then I started losing water pressure. I checked the oil and it seemed fine so I went and got some regular gas and still the water pressure isnt where it should be. While it was running the oil dipstick came loose (because I didnt have it on all the way) and it seemed like there was a lot of crankcase pressure. I started thinkin I might have destroyed my rings. Is that possible? I havent ran a compression check yet. I might try that tonight. Has anyone else heard of such a thing?
